Summary

Select ui.Link(c, "", url) when the actual SDK build parent is text (Context.InTextFlow()), including registered extension text hosts; otherwise preserve standalone LinkBase row/column/icon layout. Keep label/children callbacks, native URL activation and adapter event bindings shared. Invalid non-text children still fail strictly, not flattened or dropped.

Pin published SDK v0.0.0-20261104233121-982f5a6791f0 from logseq/mygo#17 and document the downstream root-module replacement (dependency replacements do not propagate). No portable constructor, wire-schema, App pin, dune or other-host changes.

Actual production baseline: fcff1ec9410bc1b8885d31cd81e92c31569b01c3. Its old target branch was deleted and current main has different ancestry, so the PR targets a review baseline ref at exact fcff with no new commits. The head contains only this five-file fix, no main upgrade. SDK head similarly contains production efb plus the approved query/docs, not later SDK IME/main work. Neither PR is to be merged in this acceptance task.

Verification

With GOWORK=off CGO_ENABLED=0, remote published SDK and no local module/workspace overrides:

• RED: the single retained Backend.View/ui.Tester regression reproduces original LinkBase -> coreRow -> kindText panic on the old adapter.
• GREEN: direct Text and extension-created Text hosts, rich text children and one URL activation; existing standalone icon/link regression passes.
• PASS (complete Git checkout): go test ./... -count=1 (8.872s), go vet ./..., Darwin/Linux/Windows go build ./..., go mod verify, gofmt and diff checks.
• PASS (remote published LUI module zip): both link regressions, readonly vet, module verification and command compilation. Its binary embeds SDK replace 982f5a6791f0.
• Full module-zip tests are not claimed: existing TestAllSupportedKindsRender needs repository-external ../../schema/mygo-manifest.json, absent from the Go submodule zip. The same test passes in the complete Git checkout; no fixture workaround added.
• Remote Origin hashes: LUI 9c3d93b79ef03fc3644d3bcb77d16f03f8f950b1; SDK 982f5a6791f08ef2d447e0f1780fc7e304ebc277.

No live Native Help acceptance claimed. Parent owns final App pins and installed/loaded provenance before GUI testing. SDK-wide locale and Windows WebView E2E baseline failures are evidenced in its PR; do not interpret green adapter checks as all SDK tests passing.
